题目：

In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent.  In contrast, in the year prior to the tax increase, sales had fallen one percent.  The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.
 
The argument above requires which of following assumptions?

选项:

A、During the year following the tax increase, the pretax price of a pack of cigarettes did not increase by as much as it had during the year prior to the tax increase.
B、The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.
C、The pretax price of a pack of cigarettes gradually decreased throughout the year before and the year after the tax increase.
D、For the year following the tax increase, the pretax price of a pack of cigarettes was not eight or more cents lower than it had been the previous year.
E、As the after-tax price of a pack of cigarettes rises, the pretax price also rises.

Maize contains the vitamin niacin, but not in a form the body can absorb. Pellagra is a disease that results from niacin deficiency. When maize was introduced into southern Europe from the Americas in the eighteenth century, it quickly became a dietary staple, and many Europeans who came to subsist primarily on maize developed pellagra. Pellagra was virtually unknown at that time in the Americas, however, even among people who subsisted primarily on maize.

Which of the following, if true, most helps to explain the contrasting incidence of pellagra described above?

For over two centuries, no one had been able to make Damascus blades—blades with a distinctive serpentine surface pattern—but a contemporary sword maker may just have rediscovered how. Using iron with trace impurities that precisely matched those present in the iron used in historic Damascus blades, this contemporary sword maker seems to have finally hit on an intricate process by which he can produce a blade indistinguishable from a true Damascus blade.

Which of the following, if true, provides the strongest support for the hypothesis that trace impurities in the iron are essential for the production of Damascus blades?

这题我选了B，我理解题目的意思是当代有个sword maker 用iron with 某杂质造出了和以前的D 那种blade一样的D blade，要证明iron里的这杂质对造这种blade很重要。B说现代这人用的iron以前人不知道。我觉得是排除了他因呀，以前的人不知道这种iron所以用的iron和现代这人用的不一样，那么现代人和古代人都能造出这种blade说明都是靠了那个“杂质”。而选项D他说的是：没那种iron以后大家就再没造那种blade了。我觉得不造的原因不仅可能因为没有那种杂质，也可能因为iron里别的因素吧？比如其他产地的iron强度不行啊之类的。。。。我的思路问题出在哪里哦。。

Which of the following statements is most compatible with Kosminsky's approach to history, as it is presented in the passage?
In explaining the foundations of the discipline known as historical sociology—the examination of history using the methods of sociology—historical sociologist Philip Abrams argues that, while people are made by society as much as society is made by people, sociologists' approach to the subject is usually to focus on only one of these forms of influence to the exclusion of the other. Abrams insists on the necessity for sociologists to move beyond these one-sided approaches to understand society as an entity constructed by individuals who are at the same time constructed by their society. Abrams refers to this continuous process as "structuring." Abrams also sees history as the result of structuring. People, both individually and as members of collectives, make history. But our making of history is itself formed and informed not only by the historical conditions we inherit from the past, but also by the prior formation of our own identities and capacities, which are shaped by what Abrams calls "contingencies"—social phenomena over which we have varying degrees of control. Contingencies include such things as the social conditions under which we come of age, the condition of our household's economy, the ideologies available to help us make sense of our situation, and accidental circumstances. The ways in which contingencies affect our individual or group identities create a structure of forces within which we are able to act, and that partially determines the sorts of actions we are able to perform. In Abrams's analysis, historical structuring, like social structuring, is manifold and unremitting. To understand it, historical sociologists must extract from it certain significant episodes, or events, that their methodology can then analyze and interpret. According to Abrams, these events are points at which action and contingency meet, points that represent a cross section of the specific social and individual forces in play at a given time. At such moments, individuals stand forth as agents of history not simply because they possess a unique ability to act, but also because in them we see the force of the specific social conditions that allowed their actions to come forth. Individuals can "make their mark" on history, yet in individuals one also finds the convergence of wider social forces. In order to capture the various facets of this mutual interaction, Abrams recommends a fourfold structure to which he believes the investigations of historical sociologists should conform: first, description of the event itself; second, discussion of the social context that helped bring the event about and gave it significance; third, summary of the life history of the individual agent in the event; and fourth, analysis of the consequences of the event both for history and for the individual. 想请张惠雯老师帮忙解答！ 阅读过程如下: 第一段： 历史社会学家PA认为社会学家研究the subject(指代上面的历史社会学)仅仅关注... 后面读不太懂，但是知道逻辑方向肯定是研究方法不对，后面一句也得到了证实。 A坚持认为社会学家必须越过这些片面的方法将社会理解成整体。说明社会学家与PA的观点相反。 PA指道这个持续的过程就是structuring 第一段没有什么能够跳的地方，但是总的就介绍了什么是structuring 第二段： 段间关系：仍然在围绕着structuring在谈 段落主旨：A认为历史来自于structuring。后 阅读过程:人创造历史。历史被形成不仅由....而且由... 在说历史的形成，说明全是细节。 偶然性事件包括，视角更加细化。什么方式创造了一个架构，还是细节。 第三段： 段间关系：还是在说A的分析研究，第二段说P对历史的观点，第三段开始说P对历史structuring的观点。 段落主旨：理不清 阅读过程：第三段越往后读，越理不清文章想说什么，就在说历史学家应该怎样才能理解这个historical structuring 但是此时跟整篇文章之间的关系我实在弄不明白。 阅读难处： 1 句子表达很抽象全是抽象词汇，很难弄懂句子究竟表达的什么意思 2文章逻辑结构似乎很松散，很难抓住要点 希望老师帮忙理一下这篇文章的主旨，文章整体想表达什么没有读出来，只知道说了一个PA提出了一个社会学研究的方法structuring，以及P对历史的观点，来自于structuring，P对历史structuring的观点，和P提出的一些理解历史structuring的建议。 文章的逻辑结构有点难理解

Although she was considered among her contemporaries to be the better poet than her husband, later Elizabeth Barrett Browning was overshadowed by his success.
这个题我明白ABD选项里“人”被“success” overshadowed的语义错误，但是D中的EBB's success与逗号后的'she was considered'会有逻辑不一致之嫌吗？前说success后说人，岂不是不一致么？
